What is VGG Image Annotator (VIA)?
VGG Image Annotator (VIA) is an open source web-based image annotation tool for easily labeling images to generate datasets for machine learning and computer vision research. It allows users to mark up images with shapes like bounding boxes, circles, polygons to identify objects or regions of interest.
Some key features of VIA include:
- Annotating images by drawing polygons, rectangles, circles, ellipses etc around objects
- Image tagging with multiple region shapes
- Zooming images for precision marking
- Exporting annotations in JSON format
- Integration with several popular machine learning frameworks like TensorFlow, Keras etc.
- Support for common image formats like JPG, PNG
- Can be hosted locally without requiring server setup
Overall, VIA is lightweight and easy to use for manually creating training data. With its customizable configurations and export options, it works well with deep learning pipelines to develop computer vision models for object detection, semantic segmentation, instance segmentation etc.
